RAZOR.

Specification of Letters Patent.

Patented Oct. 7, 1919.

Application filed. February 21, 1918. Serial No. 218,442.

To all whom it may concern:

Be it known that I, 'WILLIAM RAMsEYER, a citizen .of the United States, residing at Excello, Butler county, Ohio, have invented certain new and useful Improvements in Razors, of which the following is a specification.

This invention has reference to the provision upon a hollow-ground razor-blade of a guard to prevent undesired transverse springing of the blade while it is being honed, and also the giving to the guard a form adding a safety feature to the end of the blade.

In the accompanying drawing, which involves a diversity of scales Figure 1 illustrates the improved blade applied to a hone, while Fig. 2 is an end view of the blade, and Fig. 3 a transverse section of the blade in the plane of line a of Fig. 1.

The blade 1 is hollow-ground as usual,

and, in the absence of my improvement, 'would be sub ect to the usual transverse springing of the blade when applied to the hone 2 unless the application be made with extraordinary care and skill. To avoid this spring, I provided the free end of the blade on both sides with an integrally formed guard 8, with faces fiat or very slightly concaved, whose contour is such as would be the contour of the general entire blade if the blade was not severely hollow-ground. This guard stifl'ens the blade transversely while it is being honed and insures the maintenance of the proper angle upon the edge of the blade. In other words, assume for the instant that the blade is not severely hollowground but that it has a cross-section corresponding substantially with the contour illustrated in Fig. 2, such a blade can be honed without any such transverse sprin ing as will interfere with the maintenance of a proper angle for the edge. In my improved razor the general blade is seen to be much more severely hollow-ground but the in razors, would carry the extraordinary thinnness of the blade up some little distance from the corner, while in the present case the presence of the guard causes the thickness of the blade to be very materially increased near the corner in comparison with what would be the case if the guard were absent and the rounding were efiected directly upon the severely concaved blade. In the illustration there is shown a similar guard at the heel of the blade, but in practice I have found that the guard at the free end of the blade will alone endow it with a satisfactory degree of transverse stiffness.

I claim 1. A razor blade having a sharp edge and thick back and transverse concavities upon each of its faces, and an integrally formed transverse guard at each face of the blade and extending from the edge to the back of the blade and having a sharp portion at the edge of the blade and of equal thickness with the back at the back of the blade and of greater thickness than the blade at all points intermediate between the edge and the back, combined substantially as set forth.

2. A structure such as defined is claimed 1 when the edge of the guard is rounded, subcopies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,
